In SharePoint Online, I have a column number and I need to create a JSON column formatting with a conditional background. But I had noticed that the JSON column formatting removes the thousands separator from a number and it doesn't display the comma separator for long number Ex: 50,000 show it as 50000.

  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "div",
"txtContent": "@currentField",
  "style": {
    "background-color": "=if(@currentField < 1000,'Orange', 'Yellow')"

How to display Thousand Separator in SharePoint JSON Column Formatting?

In SharePoint Online / 2019, The JSON Column Formatting removes the thousand separators (comma) even if you have set the number of decimal places in the SharePoint Number column settings.

So, in JSON Column Formatting, you can't format the number column to show the thousand separator! Instead, you should use a calculated column and apply the same JSON Column Formatting on the newly created SharePoint calculated column.


  1. in Your SharePoint List, Create a new calculated column.
  2. In the calculated column formula add the below formula

     =TEXT(Your Number Column,"#,###")
  3. In the same column setting page, at the Column Formatting, paste the same JSON Column Formatting.
